Blood serum concentrations of gonadotropins and α-subunit in patients with gonadotropinomas in relation to the immunoreactivity of pituitary adenoma.
Conclusions Although "silent" gonadotropinomas constitute a frequent subtype of pituitary adenomas, the "active" (i.e. manifesting by gonadotropin excess) are rare (approx. 4% of all pituitary adenomas). Gonadotropinomas are difficult to diagnose before surgery. The measurement of gonadotropins including αSU is needed but often not sufficient for presurgical diagnosis.
